The Missing ~ 11-Year Signal

Dr. Nir Shaviv and others strongly believe that there is an ~ 11-year solar signal visible in the sea level height data. I don’t think such a signal is visible. So I decided to look for it another way, one I’d not seen used before.

Heat release from stagnant deep sea helped end last Ice Age

he build-up and subsequent release of warm, stagnant water from the deep Arctic Ocean and Nordic Seas played a role in ending the last Ice Age within the Arctic region, according to new research led by a UCL scientist.

Climate changes and solar cycles recorded at the Holocene Paraná Delta, and their impact on human population

Results suggest that aside the solar forcing, both short and medium term climate changes controlled delta evolution. An important learning is that a slight cooling would turn the highly productive pampas, into that unproductive desert and, given the lack of artificial irrigation systems, changing present-day warmhouse into a cooling cycle might be economically catastrophic for the region.

Natural climate change is less predictable than thought

Doctoral research by Tiuri Konijnendijk shows that the climate responds less predictably to natural influences than the literature assumes. While these findings will not help predict sea level rises over the next century, it will contribute to the knowledge regarding natural variation in the climate system.

Cataclysmic Cosmic Collision Triggered Global Cooling about12,800 Years Ago

At the end of the Pleistocene period, approximately 12,800 years ago­ — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas. New research by UC Santa Barbara geologist James Kennett and an international group of investigators has narrowed the date to a 100-year range, sometime between 12,835 and 12,735 years ago. The team’s findings appear today in the Proceedings of the National Academy of Science.

Study Finds Long Term Solar Cycle and Predicts Cooling

New research claims to have found evidence of long term oscillations in solar activity which span around 9,500 years and affect the climate. Solar activity levels are declining as a result of this cyclical pattern which will have a cooling impact on the Earth’s climate this century, separate to the affects of human-driven climate change and volcanoes, according to the research which has been published in a paper in the journal Earth System Dynamics.

Ice Age Megafauna Extinction Coincide With Mysterious Climate Cycles – Forbes

A recent paper in Science by University of Adelaide scientist Alan Cooper and coauthors uses ancient DNA, radiocarbon dating, and detailed statistics to show that humans may have just been the final nail in the extinction coffin for lots of of these animals as their extinctions are more closely tied to climate cycles than the arrival of humans.
